$$\sin^{2}{\left(x \right)} + \frac{3}{x^{4}}$$

sin(x)^2 + 3/x^4

Detail solution

Differentiate $\sin^{2}{\left(x \right)} + \frac{3}{x^{4}}$ term by term:
1. Let $u = \sin{\left(x \right)}$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(x \right)}$ :
  1. The derivative of sine is cosine:
    
    $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
  The result of the chain rule is:
  
  $2 \sin{\left(x \right)} \cos{\left(x \right)}$
4. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $\frac{1}{x^{4}}$ goes to $- \frac{4}{x^{5}}$
  So, the result is: $- \frac{12}{x^{5}}$
The result is: $2 \sin{\left(x \right)} \cos{\left(x \right)} - \frac{12}{x^{5}}$
Now simplify:

$\sin{\left(2 x \right)} - \frac{12}{x^{5}}$

The answer is:

$\sin{\left(2 x \right)} - \frac{12}{x^{5}}$
